ABSTRACT:
Moldings can be produced from a polymer powder containing at least one block polyetheramide containing an oligoamide dicarboxylic acid and a polyetheramine; wherein the powder is suitable for use in a layer-by-layer process in which regions of a powder layer are selectively melted via introduction of electromagnetic energy.
